MACHINE FOR UPSETTING TIRES.

SPECIFICATION formingpart of Letters Patent No. 247,667, dated September 27, 1881.

Application filed May 31, 1881. -(No model.)

To all whom it may concern Be it known that I, GEORGE BILIBBY, a citizen of the United States, residing at Lehigh, in the county of Webster and State of Iowa, have invented certain new and useful Improvements in Tire-Shrinkers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of devices known as tire-shrinkers, and the novelty consists in the peculiar construction and combination of the parts making up the machine, all as will now be more fully disclosed and explained.

In the accompanying drawings, A denotes the bed of the machine, mounted on legs a. In this bed A, in suitable openings, at, are the pieces B, adapted to be moved on the ways I) bymeans of the shaft 0, properly hung beneath bed A and operated by arm 0. To this shaft are connected the four links D, two on each side. Theselinks severally unite the shaft to the ends of the vertical crank-shafts e of the serrated cam-shaped clamping-jaws E, which shafts 0 pass down through the movable pieces B. Thus when the shaft 0 is rotated motion is communicated to the pieces B to move them back or forth, and also to the shrinkers to revolve them to or from each other. By this construction is secured great power, while at the same time the several parts can be operated in the easiest manner.

This device occupies but small space, and, if desired, other operative parts, such as relate to bending tires and punchingand cuttingsame, may be attached to or mounted on the same bed or table.

This device is easily operated, and since the power developed is very great and the construction of the same quite simple, it is evident that a very excellent machine or device is pro-
